Is there a dummies guide to the structure of an icc profile?

Something dumbed down so someone with my limited experience can
understand it.

I would imagine at some location in the file there is a table of input
colors and output colors. Am I right in this assumption or is it a
formula instead of a lookup table?

Does it use both possibly?

I'd like to gain enough information that I could direct a file pointer
to locations in the file, read a defined number of bits/bytes and
interpret what's there.

And...

How complex is the math used in moving one color to another color space
in one of the popular rendering intents? Are there examples of these
equations available outside of proprietary technology?

I'd love to make a profile reader just for personal entertainment.

tia.
